Airlines & air cargo: Industry Primer

1. Scope & definitions

Airlines & air cargo comprise carriers that transport passengers and freight via scheduled and charter operations, alongside the systems and partners that enable planning, distribution, operations, maintenance, safety, and customer service. Passenger airlines operate domestic and international networks on hub‑and‑spoke or point‑to‑point models. Air cargo is carried in dedicated freighters and in the belly holds of passenger aircraft; integrated express carriers combine air fleets with ground networks for time‑definite delivery.

Business model archetypes include full‑service network carriers (FSNCs/legacies), low‑cost carriers (LCCs), ultra‑low‑cost carriers (ULCCs), hybrid carriers, regional feeders, leisure/charter operators, and all‑cargo/freighter airlines. Alliances, joint ventures (JVs), interline and codeshare agreements extend network reach and revenue opportunities. ACMI/charter (aircraft, crew, maintenance, insurance) providers lease lift to airlines and shippers.

Core industry measures: ASKs/ASMs (Available Seat Kilometers/Miles), RPKs/RPMs (Revenue Passenger Kilometers/Miles), load factor (%), yields (revenue per RPK/RPM), PRASM/RASM (passenger/total revenue per ASM), CASM/CASK (cost per ASM), unit cost ex‑fuel, block hours, aircraft utilization (daily hours), on‑time performance (OTP), completion factor, mishandled baggage per 1,000 pax, NPS/CSAT. Cargo uses ATKs (Available Tonne‑Kilometers), RTKs (Revenue Tonne‑Kilometers), weight load factor, yields (revenue per RTK), and contribution per flight.

Regulatory & safety: ICAO (Annexes), IATA operational standards; national regulators (FAA, EASA and NAA equivalents) govern certification (AOC), airworthiness, crew duty limits (FTL), operations, and consumer protections. Air traffic management (ANSPs) and slot coordination (IATA WSG/WASG) shape capacity. Environmental frameworks include CORSIA and regional schemes (e.g., EU ETS), noise and local air quality rules. Security follows ICAO Annex 17 and local requirements.

Technology & distribution: PSS (passenger service systems), RMS (revenue management), NDC (New Distribution Capability) and ONE Order (retailing/fulfillment simplification), DCS (departure control), crew systems, MRO/maintenance IT, cargo TMS and e‑AWB/e‑freight, self‑service and biometrics. Payments and fraud management comply with PCI DSS and SCA where applicable.
